IMPROVEMENT IN FURNlTURE-CA STERS.

Specification forming part of Letters Patent No. 155,763, dated October6, 1874; application filed September 5, 1874.

CASE N.

To all whom it may concern Be it known that I, ()EVEDRA B. SHELDON, ofNew York city, in the county and State of New York, have invented a newand Improved Furniture-Caster, of which the following is a specificationThis invention consists of cylindrical antifriction rollers interposedin a novel manner between the ring or flange of the socket-tube for thespindle and the topplate of the horns,

the said rollers being held in place by slotted disk, which confines theinner ends close against the spindle, thereby enabling the top plate ofthe horns to aflord, by its ordinary size, ample surface for the rollersto run on, and thus saving the necessity of enlarging it; and the outerends of the rollers are confined by the outer ends of the radial slotsin the disk, so that the forming of a recess in the flange of thespindle-socket for that purpose is avoided. a

Figure 1 isa sectional elevation of my improved caster, taken on theline as w of Fig. 2; and Fig. 2 is a horizontal section taken on theline 3 y of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is the socket for the caster-spindle B, and O is the flange of saidsocket, which I make plain or flat, in the simplest and cheapest form.D-represents the cylindrical rollers, which I introduce between thebottom of the flange and the top of the plate E of the horns F. G

represents the disk for confining the rollers between said flange andthe horn-plate; also, for preventing them from running together. Thisdisk I make with radial slots H for the rollers, beginning at thecentral .hole in the disk, and extending outwardly only so far as thelength of the rollers, and terminating sufficiently short of theperiphery to enable the disk itself to confine the rollers againstworking out-ward, and thus saving the necessity of making any changeeither in the hornplate or the flange from the" ordinary con struction;also, saving the providing of any means other than the disk forconfining the rollers, whereby the construction is rendered the mostsimple, and the arrangement is, at the same time, as permanent anddurable as any, if not more so.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The interposed slotted disk G between the top of the horn-plate E andthe bottom of the socket;flange C, said plate and flange being arrangedto confine the rollers D next to the spindle, and without a socketeither in the horn-plate or the socket-flange, as shown and described,for the purpose set forth.
